“Nelly is the victim of a completely fabricated allegation,” Rosenblum said in a statement to Variety. “Our initial investigation clearly establishes this allegation is devoid of credibility and is motivated by greed and vindictiveness. I am confident, once this scurrilous accusation is thoroughly investigated, there will be no charges. Nelly is prepared to address and pursue all legal avenues to redress any damage caused by this clearly false allegation.”

According to the Auburn Police Department, officers arrested the Grammy winner, whose real name is Cornell Iral Haynes Jr., on Saturday at 3:48 a.m. in his tour bus. He was taken into custody and booked less than an hour later.

Nelly had performed at the White River Amphitheater in King County just hours before the incident, which is still being investigated by Auburn Police. The rapper is on tour with Florida Georgia Line and was scheduled to perform on Saturday night in Ridgefield, Wash.

The musician is best known for his hits “Hot in Herre,” ”My Place,” and “Over and Over.”
